Watch: 'Sheep cyclone' traps car

A video of sheep running around a moving car in Russia went viral this week. It's easy to see why.

It's not just big cities that suffer from traffic jams. They can even happen in more rural areas like Russia's Caucausus region — albeit with some minor differences:

This video has spread wildly since it was uploaded to YouTube. It was filmed in the Caucausus, according to Digital Journal, but little else is known about it — including the animals' motivation.

Australia's Nine Network News takes a crack at explaining the "sheep cyclone," though, coaxing this theory from a sheep breeder in New South Wales: "Sheep who've been hand-fed at some stage in their life think they're about to get fed whenever they see a vehicle. They will get used to chasing and circling moving vehicles. They have no appreciation of the danger involved."
